CHAPTER 13
FIREBOX AND OTHER COMPONENTS
Firebox
Principles of the Firebox
Wood is burned inside the firebox to generate heat.
This heat is absorbed into the HTF in the water
jacket. The firebox and water jacket are one welded
component and can be replaced. When the HTF is up
to temperature and the combustion air blowers are off,
the firebox must be airtight.
Operation of the Firebox
Temperatures within the firebox can reach 2000
degrees Fahrenheit. Smoke exits from the firebox
into the flue. During normal operation, there will be a
slight buildup
of black creosote on the firebox walls. This buildup will sometimes appear flaky.
Maintenance / Result
Wood should not be thrown into the firebox in a rough manner. Creosote should never have
to be scraped off the firebox walls.
